Check the label format for character placement outside the
dimensions of the label; all row/column values must allow
enough space for the height/length of the characters and
bar codes to be printed within the format size.
The available memory may have been exceeded by the
memory requirement of the label format. Try reducing the
memory allocated to either the internal module or
scaleable font caches, see Section 4.5.)
If using serial communications, ensure that the interface
cable meets the requirements found in Section 2.1.2.
Information may be formatted outside the label dimensions.
Check your software program label size. For display-
equipped printers also check the values in the menu for Print
Control / Column Offset and Print Control / Custom
Adjustments / Column Offset; see Section 4.5.
Verify that the AC power cord connection has been made
at both the outlet and the printer; also, ensure the power
switch is 'On'.
Verify that the AC outlet is functioning, or try moving the
printer to another AC circuit.
The AC cord may be damaged; replace it.
The line fuse may be blown; call for service.
